WlNDLASS-CLAMP DEVICE FOR RAISING WAGON-BEDS.

SPECIFICATION forming part of Letters Patent No. 598,886, dated February8, 1898. Application filed. October 14, 1897. Serial No. 655,141. (Nomodel.)

To aZZ whom it may concern.-

Be it known that I, ANTHONYW. J AOKSON, a citizen of the United States,residing at Paris, in the county of Henry and State of Tennessee, haveinvented a new and useful Improvement in Windlass-Clamp Devices forRaising Wagon-Bodies, of which the following is a specification.

For raising wagon beds or bodies from and lowering them upon therunning-gear of wagons I have produced an improved clamp device for theWindlass-rope wherein provision is made for rendering more secure theattachment of the Windlass device to the end of the wagon-body, as Iwill now describe in connection with the accompanying drawings, in which7 Figure 1 shows in side view a wagon-body suspended by my improvedWindlass attachment. Fig. 2 shows the Windlass device in perspective.Fig. 3 shows in enlarged sectional view the Windlass device as appliedto the wagon-body.

The frame of the Windlass device is formed of a single casting ofconnected bars 1 1, between which the windlass-drum 2 is mountedhorizontally and is provided at its outer end with a ratchet-wheel 3,which is engaged by a pawl 4, pivoted on the outer bar, to hold theWindlass when rope 5 is wound thereon in raising the wagon-body. Belowthe windlass the inner bar is turned inward toward the outer bar as ahorizontal jaw-forming arm 6, which joins the bottom bar 7 by a verticalpart 8, standing about mediately of the width of the frame and formingat the lower inner side of the casting a rectangular recess,whereby thecasting is fitted over and upon the wagon-bottom boards 9 and undercross-bar 10. To the transverse bar 10 and to the projecting part of thebottom of the body the Windlass device is adapted to be secured, so thatthe horizontal jaw-forming arm 6 will rest upon the projecting ends ofthe bottom boards. The lower connecting frame part 7 extends under thebody and is bifurcated to form two upward-standing arms 11 11, adaptedwhen the device is applied to pass behind the cross-bar 10in position toengage it. Each arm of the forked part has a vertical screw 12 forengaging the under side of the bottom cross-bar to clamp the devicevertically upon the body, while the Vertical recess-forming part 8 has ahorizontal screw 13 for engaging the outer side of the bottom cross-.bar to clamp the device horizontally thereto by drawing the upper endsof the forked arms against the inner side of said cross-bar. Thishorizontal clamp is important to prevent the device from being twistedfrom the hold'given by the vertical clamp-screws because the weight ofthe wagon constantly tends to wrench the device off. To render theengagement of the forked arms more eifective, they are provided withspurs 14:, which under the clamping action of the screws 13 are causedto bite into the cross-bar. The jaw-forming arm 6 haslaterally-extending arms 15,which, with the jaw, form a transversebearing upon the projecting end boards of the bod-y, and these arms 15correspond in position and cooperate with the forked arms 1 1 and theirclamping-screws 12 to prevent the tilting of the body in being raisedand to hold it firm and secure. The upper bar of the casting has a slotthrough which the rope passes from the Windlass and causes the rope tobe wound evenly thereon. From the Windlass the rope passes over thepulleys 16, which maybe hung to the ceiling of the shop or from asuitable beam, and the other end of the rope is connected by suitablebail or suspending device 17 to the other end of the wagon-body, so thatby turning the Windlass the body is raised and lowered as required.

It will be understood that the forked arms and the recess-forming clampare arranged and proportioned to permit the said arms to be placedbehind the bottom cross-bar as the device is seated on the projectingend of the body.

I claim- A Windlass-clamp device,the frame of which is formed with theupper jaw-arms 15, and the lower forked arms, the latter provided withvertical clamping-screws corresponding .in position to the upper lateraljaw-arms, the

said forked arms extending upward and provided with spurs, and theclamping-screws 13 .in the Vertical part 8 of the horizontal jaw asshown and described. I

In testimony whereof I have hereunto signed this specification in thepresence of
